3 <p>Roman numerals are a way of expressing numbers using symbols. I, V, X, L, C, D, and M are the symbols we use. Roman Numerals are used in royal titles, book names, sequences, and so on. Here we will discuss Roman Numerals, rules, and examples.</p>

4 <h2>What is 25 in Roman Numerals?</h2>

5 <p>The royal titles, such as Henry I, Henry II, and so on, have you noticed the names and wondered what these<a>symbols</a>(I and II) represented? Those are the Roman Numerals. Earlier people used to count using fingers, sticks, bones, etc. When life became complex, a<a>standard form</a>was required to count. Ancient Romans used the Roman Numeral system to count. I (1), V (5), X (10), L (50), C (100), D (500), and M (1000) are the symbols we use to count.</p>

6 <p>In Roman Numerals, we use XXV to represent 25, where XX is 20, and V is 5. Let’s learn more about Roman numerals and how we write them. </p>

7 <h2>Basic Rules for 25 in Roman Numerals</h2>

8 <p>There are certain basic rules to write a<a>number</a>in Roman Numerals. In this section, let’s discuss some basic rules that need to be remembered when writing a number in Roman numerals. </p>

9 <p><strong>Rule 1: Addition Method</strong></p>

10 <p>The<a>addition</a>method is used when the smaller number is placed after the larger number; then it is the addition method. For example, XXV → XX + V → 20 + 5 = 25.</p>

11 <p><strong>Rule 2: Repetition Method</strong></p>

12 <p>To write a large number, there are certain Roman Numerals that can be repeated up to three times. III → 3. </p>

13 <p><strong>Rule 3: Subtraction Method</strong></p>

14 <p>If a small number is followed by a large number in Roman Numerals, we subtract the smaller number from the large number; it is a<a>subtraction</a>method. For example, IX → X - I → 10 - 1 = 9. </p>

15 <p><strong>Rule 4: Limitation Rule</strong></p>

16 <p>The symbols cannot be repeated more than three times, and some symbols like V, L, and D cannot be repeated. For example, we won't write VV for 10; instead, we use X, and for 8, we write VIII, not IIIIIIII. </p>

17 <h2>How to Write 25 in Roman Numerals</h2>

18 <p>Let’s now learn how to write 25 in Roman Numerals. Follow these methods to write the number in Roman Numerals.</p>
